Tetra Corporation has been developing its electrohydraulic
technology over the past 17 years. Numerous patents protect this technology.
Approximately $9.4 million has been invested in developing Tetra Corporation's
eletrohydraulic technologies.

The Electrohydraulic Process

An electrical
spark is created in water and a pulse of electricity at high
peak power is passed through the spark. This forms rapidly expanding
plasma in the water that creates a shock wave. These shock waves
are so powerful they can crush rock This shock wave can be controlled
to crush the rock just ahead of the drill to less than 1 mm
in size. The device drills into the rock by repeating the shock
wave 10 – 50 times per second.
